SUBTTL CONVERT MONGEN SYMBOLS
REPEAT 0,<
;THIS SECTION CONVERTS NEW MONGEN SYMBOLS TO OLD MONGEN SYMBOLS
;SO THAT THE REST OF COMMON AND MONITOR CAN STILL USE THE OLD
;SYMBOLS. THIS WAS DONE RATHER THAN CONVERTING ALL OF THE
;MONITOR TO NEW SYMBOLS FOR TWO REASONS:
; 1. IT IS EASIER AND FASTER AND LESS LIKELY TO INTRODUCE BUGS, AND
; 2. IT ALLOWS CUSTOMERS TO USE OLD MONGEN WITH A MINIMUM
;OF TROUBLE: ONLY A FEW EXTRA SYMBOLS MUST BE DEFINED.
;THE MONITOR WILL PROBABLY BE CONVERTED TO THE NEW MONGEN SYMBOLS
;AFTER THE 5.04 RELEASE. THE ORDER HERE PARALLELS THE OLD
;MONGEN ORDER.

STEPS TO WRITE NEW SOFTWARE FOR A NEW KONTROLLER TYPE
1. DECIDE ON A 2 LETTER MNEMONIC (FH,MD,DP,FS,RP,RN ARE TAKEN, DR RESERVED FOR DRUM)
2. WRITE KONTROLLER DEPENDENT ROUTINE (EG XX'XKON)
3. ADD A KONTROLLER DEPENDENT MACRO XX'KON IN COMMOD
4. ADD ANOTHER REPEAT LOOP IN CHANNEL MACRO (CHNCB) TO CALL KONTCB MACRO IN COMMOD
5. ADD MNEMONIC DEFINITION FOR TOTAL NUMBER OF KONTROLLERS TO COMMON (EG FHDN FOR FH)

LOGIC==0 ;MAKE SURE PROGRAM LOGIC FLOW IS NEVER ASSEMBLED
REPEAT LOGIC,<
THE PROGRAM LOGIC FLOW FOR THE LEVEL D DISK SERVICE IS PRODUCED
FROM THE PROGRAM LISTINGS BY USE OF A TECO MACRO. ALL TEXT INSIDE
REPEAT LOGIC,< AND > IS COPIED INTO THE MANUAL. PUTTING THE PROGRAM
LOGIC FLOW INTO THE LISTING MAKES IT EASIER TO KEEP THE LOGIC FLOW
UP TO DATE WITH THE ACTUAL CODE.
THE PROGRAM LOGIC FLOW IS WRITTEN IN A CLOSE TO ENGLISH MANNER
FOLLOWING SYNTACTIC RULES OF THE MAD (MICHIGAN ALGORITHMIC DECODER)
LANGUAGE. A MINIMUM OF ACTUAL PROGRAM SYMBOLS ARE USED IN THE STATEMENTS.
HOWEVER THE SYMBOLIC TAGS DO CORRESPOND TO THE ONES USED IN THE PROGRAM
FOR EASE OF RELATING A PIECE OF THE FLOW TO THE CODE. ENGLISH HAS BEEN
USED FOR A NUMBER OF REASONS. FIRST, THE ENGLISH FLOW WAS PRODUCED
BEFORE THE CODE WAS WRITTEN. IN THIS WAY THE DESIGN OF THE DECISION
LOGIC WAS DECOMPOSED FROM THE PROBLEM OF CODING, SUCH AS NAMING SYMBOLS,
BITS, AC USAGE AND SUBROUTINE ORGANIZATION. SECONDLY THE READER
INTERESTED IN UNDERSTANDING THE FLOW DOES NOT HAVE TO LEARN THE ENTIRE
FLOW BEFORE UNDERSTANDING A PART OF IT; HE DOES NOT NEED TO LEARN AND
REMEMBER A LOT OF SYMBOLS AND THEIR MEANING. A FEW ABBREVIATIONS HAVE
BEEN USED AND THEY ARE:
STR FILE STRUCTURE - A LOGICALLY COMPLETE, SELF CONTAINED,
AND REMOVABLE PART OF THE DISK SYSTEM. ALL FILE
RETRIEVAL POINTERS STORED IN AN STR REFER TO DISK
ADDRESSES WITHIN THAT STR.
MFD MASTER FILE DIRECTORY - LISTS ALL PROJECT PROGRAMMER
NUMBERS IN A SINGLE FILE STRUCTURE ALONG WITH THE DISK
ADDRESS WITHIN THE FILE STRUCTURE OF THE ASSOCIATED UFD.
UFD USER FILE DIRECTORY - LISTS ALL FILES BELONGING TO A
USER (IDENTIFIED BY A PROJECT-PROGRAMMER NUMBER PAIR)
IN A SINGLE FILE STRUCTURE ALONG WITH THE DISK ADDRESS
THE FILE STRUCTURE OF THE ASSOCIATED FILE.
RIB RETRIEVAL INFORMATION BLOCK - ALL FILES (INCLUDING THE
MFD AND UFD) HAVE A 128 WORD DISK BLOCK (RELATIVE BLOCK 0
OF THE FILE) WHICH CONTAINS ATTRIBUTES OF THE FILE
ALONG WITH POINTERS TO THE CONTIGUOUS GROUPS OF 128
WORD DATA BLOCKS OF THE FILE. THE MFD AND UFD REALLY
POINT TO THE RIB WHICH IN TURN POINTS TO ALL PARTS OF
THE FILE.
>
; THERE IS A POTENTIAL CONFUSION BETWEEN 3 KINDS OF DISK POINTERS:
; A. COMPRESSED UFD POINTERS (CUP) - FOUND ONLY IN DIRECTORIES,
; POINT TO UNIT AND FIRST CLUSTER.
; B. CLUSTER POINTERS - FOUND MOST EVERYWHERE - POINT TO CLUSTERS.
; C. BLOCK POINTERS - SELDOM FOUND IN CORE OR ON DISK.
; EXEPTIONS: RIBUFD, RIBSLF,UNIBLK, HOMSLF, SAFSLF
;USE OF PREFIXES IN DEFINING SYMBOLS
;THERE ARE A NUMBER OF DATA AREAS IN CORE OR ON THE DISK WHICH HAVE
;SYMBOLS WHICH DEFINE EACH POSITION IN THE AREA. TO MAKE IT
;CLEAR WHICH AREA A SYMBOL IS FROM, EACH SYMBOL HAS A THREE LETTER,
;PRONOUNCEABLE PREFIX. THIS PREFIX IS DIFFERENT WHEN AREA IS IN CORE
;FROM WHEN THE SAME DATA IS ON THE DISK. THE FOLLOWING TABLE DEFINES
;THE PREFIXES:

CONVENTIONS ABOUT SYMBOL PREFIXES. WITHIN CORE BLOCKS THERE ARE THE
FOLLOWING TYPES OF SYMBOLS:
ACC,NMB 1. RELATIVE WORD ADDRESS
ACY 2. RELATIVE OR ABSOLUTE ADDRESS OF A WORD CONTAINING A BYTE POINTER
ACS 3. SIZES OF A BYTE
ACP 4. BIT WHICH IS IN RIGHT MOST POSITION OF BYTE OR BIT ITSELF.
NOTE: BIT 35 IS DEFINED AS 1, BIT 18 AS 400000,
BIT 17 AS 1, ETC.
ACN 5. BIT NUMBER (0...35) OF RIGHT MOST BIT OF BYTE
(USED TO DEFINE SYMBOLS FOR BYTE POINTERS)
(DO NOT CONFUSE WITH ACP)
ACR 6. BITS IN A BYTE AFTER IT HAS BEEN RIGHT JUSTIFIED IN AN AC.
ACV 7. VALUE OF A CODE (MORE THAN 1 BIT FLAG) RIGHT JUSTIFIED IN AN AC
FOR USE IN LDB AND DPB
ACM 8. MASK FOR BYTE, I.E. ONES IN EVERY BIT POSITION
(BEFORE BYTE IS RIGHT JUSTIFIED)
ACJ 9. -NO. OF PLACES TO RIGHT JUSTIFY BYTE IN AC (ALWAYS NEG.)
THE RELATIVE WORD ADDRESS HAS THE FULL 3 LETTER PREFIX OF THE CORE BLOCK.
MANY PREFIXES END WITH B STANDING FOR BLOCK, (NOT BYTE OR BIT).
THE MNEMONIC FOR BYTE IS Y(ITS SECOND LETTER - SORRY ABOUT THAT), FOR SIZE
IS S, FOR POSITION IS P, AND FOR RIGHT-JUSTIFIED IS R.

SUBTTL DATA STRUCTURE DESCRIPTION
;THE FOLLOWING CORE DATA BLOCKS ARE LINKED TOGETHER TO DESCRIBE
;AN ARBITRARY CONFIGURATION OF FILE STRUCTURES ON AN ARBITRARY
;CONFIGURATION OF CHANNELS, KONTROLLERS, POSITIONERS, AND UNITS:
;EACH SYSTEM HAS:
;SYS: DATA LOCATIONS AND BYTE POINTERS PER SYSTEM
;STR: 1 OR MORE FILE STRUCTURES PER SYSTEM
;CHN: 1 OR MORE CHANNELS (CAN BE SHARED BY MORE THAN 1 FILE STRUCTURE)
;CON: 1 OR MORE KONTROLLERS (DIFFERENT TYPES ON SAME CHANNEL, BUT SAME
; TYPES IN A GIVEN FILE STRUCTURE) PER CHANNEL
;UNI: 1 OR MORE UNITS PER KONTROLLER
;DEV: 1 OR MORE QUEUED POSITION REQUESTS PER UNIT
; 1 OR MORE QUEUED TRANSFER REQUESTS PER CHANNEL
;PPB: 1 OR MORE ACTIVE OR DORMANT PROJ-PROG NOS BLOCKS PER SYSTEM
;UFB: 1 OR MORE ACTIVE OR DORMANT UFD BLOCKS (1 FOR EACH STR) PER PROJ-PROG NO.
;NMB: 1 OR MORE ACTIVE OR DORMANT FILE NAME BLOCK (INDEPENDENT OF STR)
; PER PROJ-PROG NO.
;ACC: 1 OR MORE ACTIVE OR DORMANT ACCESS BLOCK (1 FOR EACH VERSION OF A FILE)
; PER FILEMANE/PROJ-PROG NO. PAIR
;THE FOLLOWING RESTRICTIONS APPLY:
; 1) FILE STRUCTURE MUST BE COMPOSED OF SAME SIZE AND TYPE DEVICES
; EXCEPTIONS - RD10 (BURROUGHS FHD) AND RM10B (BRYANT DRUM) MAY
; BE IN SAME FILE STRUCTURE SINCE ON SAME CONTROLLER; ALSO RP01
; AND RP02 (MEMOREX DISK PACK)
; 2) FILE STRUCTURE MAY BE COMPOSED OF ONE OR MORE CONTROLLERS
; (OF THE SAME TYPE.)
; 3) EACH UNIT CAN BE A MEMBER OF ONE AND ONLY ONE FILE STRUCTURE
; 4) MORE THAN ONE CONTROLLER IN THE SAME OR DIFFERENT FILE STRUCTURE
; ON THE SAME CHANNEL (SOFTWARE WILL DO LATENCY OPTIMIZATION ON A
; CHANNEL BASIS RATHER THAN A CONTROLLER BASIS)
;SOME CORE BLOCKS ARE LINKED TOGETHER BY A ONE DIRECTION STRING OF
;POINTERS TERMINATED WITH A 0. A "LIST", PTR IN LH. OTHER CORE BLOCKS
;ARE LINKED TOGETHER BY A ONE DIRECTIONAL STRING OF POINTERS WHICH
;CLOSES ON IT SELF. A "RING", PTR IN LH. STILL OTHER BLOCKS POINT
;BACK UP THE TREE TO THEIR FATHER OR THEIR GRANDFATHERS.
;UPWARD POINTERS TEND TO BE IN RH WITH BITS 13-17=0 SO INDIRECTION
;CAN BE USED.
;THE REST OF THE CORE BLOCKS ARE POINTED TO BY ONE CORE BLOCK TABLE
;OF POINTERS - A"FANOUT TABLE" THESE ARE IN RH.
;STATIC ADDRESS OF CORE DATA BLOCKS ASSEMBLED IN OTHER DATA BLOCKS:
;FANOUT TAB - SYS POINTS TO ALL STR TABLES (TABSTR) (MAX.14)
;FANOUT TAB - EACH KON POINTS TO ALL PHYSICAL UNI WITHIN KONTROLLERS (KONTAB)
;LIST - EACH STR LINKS TO NEXT STR WITHIN SYS (LH STRSYS)
;LIST - EACH UNI LINKS TO NEXT UNI WITHIN STR (LH UNISTR)
;LIST - EACH UNI LINKS TO NEXT UNI WITHIN SYS (LH UNISER)
;RING - EACH UNI LINKS TO NEXT UNI WITHIN CHN (LH UNICHN)
;RING - EACH UNI LINKS TO NEXT UNI WITHIN KON (LH UNIKON)
;UPWARD POINTER - EACH DEV POINTS TO ITS UNI (RH DEVUNI)
;UPWARD " - EACH UNI POINTS TO ITS CHN (RH UNICHN)

A SERIES OF MACROS ARE INCLUDED HERE FOR GENERATING CHANNEL, KONTROLLER,
AND UNIT CORE BLOCKS. THE VARIOUS CORE BLOCKS ARE LINKED TOGETHER
APPROPRIATELY; THE NUMBER OF EACH TYPE AND APPROPRIATE LINKAGE ARE
DETERMINED BY SYMBOLS GENERATED BY MONGEN. SYMBOLS GENERATED ARE:
CHNN TOTAL NUMBER OF DATA CHANNELS (DF10) FOR DISKS
CHANNELS ARE NUMBERED FROM 0 TO CHNN - 1
CNFH NUMBER OF FIXED HEAD KONTROLLERS ON CHANNEL N
CNDP NUMBER OF DISK PACK KONTROLLERS ON CHANNEL N
CNMD NUMBER OF MASS FILE (BRYANT DISK) KONTROLLERS ON CHANNEL N
KONTROLLERS OF EACH TYPE ARE LETTERED A,B,C, ETC., SO
THE FIRST DISK PACK KONTROLLER IS DPA, THE SECOND DPB, ETC.
XXYUN NUMBER OF UNITS ON KONTROLLER XXY
THE CHNCB MACRO GENERATES A CHANNEL CORE BLOCK, THEN CALLS MACROS TO
GENERATE KONTROLLER AND UNIT CORE BLOCKS. ITS ARGUMENT IS THE CHANNEL NUMBER,
IN ASCII. CHNCB CALLS MACRO KONTCB FOR EACH KONTROLLER ON THE CHANNEL. THERE
IS A REPEAT LOOP FOR EACH KONTROLLER TYPE, REPEATED CNXX TIMES, WHERE N IS THE
CHANNEL NUMBER AND XX IS THE KONTROLLER TYPE, EACH LOOP CALLING KONTCB ONCE.
THE ARGUMENTS FOR KONTCB ARE THE KONTROLLER TYPE, A LIST CONTAINING THE LETTERS
TO IDENTIFY SUCCESSIVE KONTROLLERS, AND THE CHANNEL NUMBER, IN ASCII.
KONTCB FIRST CALLS MACRO XXKON TO GENERATE A KONTROLLER CORE BLOCK FOR THE
KONTROLLER, THEN REPEATS XXYUN TIMES CALLING UNITCB MACRO TO GENERATE UNIT CORE
BLOCKS FOR THE KONTROLLER. ARGUMENTS FOR XXKON ARE KONTROLLER TYPE (XX),
KONTROLLER IDENTIFIER, AND THE ASCII VALUE OF SYMBOL XXNUM, WHICH IS INCREMENTED
FOR EACH KONTROLLER OF TYPE XX. XXKON FORMS SYMBOL XX'XXNUM (XX0, XX1, ...),
WHICH IS USED AS THE DEVICE CODE FOR THE KONTROLLER. ARGUMENTS FOR UNITCB
INCLUDE KONTROLLER TYPE, KONTROLLER IDENTIFIER, UNIT NUMBER, AND SYMBOLS TO USE
IN LINKING THE UNIT CORE BLOCKS TOGETHER (SEE UNITCB MACRO).
EACH XXKON MACRO SHOULD CALL THE KONKON MACRO FOR THE KONTROLLER INDEPENDENT
PART OF THE KONTROLLER CORE BLOCK. ARGUMENTS FOR KONKON MACRO ARE KONTROLLER
TYPE (XX), KONTROLLER IDENTIFIER (Y), AND SYMBOL XX'NUM WHICH IS THE DEVICE CODE
FOR THE KONTROLLER. NUM IS INCREMENTED FOR EACH KONTROLLER OF TYPE XX.
THE UNIT CORE BLOCKS ARE LINKED IN THREE DIFFERENT WAYS. ALL UNIT CORE
BLOCKS ON A KONTROLLER ARE LINKED IN A RING (THE LAST POINTS TO THE FIRST),
ALL UNIT CORE BLOCKS ON A CHANNEL ARE LINKED IN A RING, AND ALL UNIT CORE
BLOCKS IN THE SYSTEM ARE LINKED IN A LIST (THE LAST LINK IS 0). TO
COMPLETE THIS LINKAGE, KONTCB CALLS MACRO KONCLS TO CLOSE THE KONTROLLER
RING, AFTER ALL UNIT CORE BLOCKS FOR THAT KONTROLLER HAVE BEEN GENERATED; CHNCB
CALLS CHNCLS TO CLOSE THE CHANNEL RING; AND AFTER ALL SYSTEM UNIT CORE BLOCKS
HAVE BEEN GENERATED, SYSCLS IS CALLED TO TERMINATE THE SYSTEM LIST.
TO ADD ANOTHER KONTROLLER TYPE XY, YOU MUST ADD ANOTHER REPEAT LOOP IN CHNCB,
REPEATING CNXY TIMES AND PASSING ARGUMENT XY TO KONTCB MACRO. KONTCB
CALLS MACRO XYKON FOR THE KONTROLLER DEPENDENT PART OF THE KONTROLLER CORE
BLOCK; THAT MUST ALSO BE SUPPLIED. XYKON SHOULD CALL THE KONKON MACRO FOR
THE KONTROLLER INDEPENDENT PART OF THE KONTROLLER CORE BLOCK.
